Pros and cons of stem cell research
This stage of pregnancy is when many birth defects or other potential issues begin. They come from unused embryos for in vitro fertilization and are not taken without consent. Until any of the techniques are proven effective and widely accessible, research will remain as that — research.
Bad things about stem cells
Adult stem cells, collected from consenting parties, should have no criticism whatsoever. Amniotic, induced pluripotent, and adult stem cells do not involve the creation or destruction of a human embryo to have them collected. The nucleus DNA is removed from a skin cell. Bush Vetoes In , H. In 3 to 5 days, the embryonic stem cells are removed. They come from unused embryos for in vitro fertilization and are not taken without consent. Each cell line that is harvested offers the opportunity to develop new treatments that may help to stop a plethora of diseases that affect humanity. Alternatives to Embryonic Stem Cells Use of adult-derived stem cells—known as induced pluripotent stem cells IPSCs —from blood, cord blood, skin, and other tissues have been demonstrated as effective in treating different diseases in animal models. When new medical treatments are proposed, they must go through multiple stages of testing. Opponents consider them as a human life, considering that they are derived from embryos. There is no evidence that embryos have lives or not so they should not be destroyed. Rejection rates are high for these therapies. List of the Pros of Stem Cell Research 1. If the patient volunteers, however, the sacrifice would be worth it.
With a greater understanding of this micro-environment, we can learn more about who we are at our very core. Inwhen the US Government took steps to limit the funding and availability of stem cell research to just 19 lines.
They believe that it is immoral to destroy a few-days-old human embryo, even to save or reduce suffering in existing human life. Actual cures are many years away, though, since research has not progressed to the point where even one cure has yet been generated by embryonic stem cell research.
Pros and cons of stem cell therapy
Article Table of Contents Skip to section Expand. Before Bush stopped federal research in , a minor amount of embryonic stem cell research was performed by US scientists using embryos created at fertility clinics and donated by couples who no longer needed them. As we move forward in this research, new pros and cons may also require additional contemplation. This way, they will understand better how cells function and will be able to apply these researches in finding other ways to cure diseases in the future. Research has been held back by factual contradictions. Embryonic stem cells are extremely flexible. Developments in Stem Cell Research In August , Harvard University scientists announced a breakthrough discovery that fuses "blank" embryonic stem cells with adult skin cells, rather than with fertilized embryos, to create all-purpose stem cells viable to treat diseases and disabilities. Adult stem cells have a determined cell type. The current treatment options for stem cells are numerous.
And since it is unsure that life exists in an embryo or not, no one should destroy an embryo without any concern or consideration. Steps in therapeutic cloning are: An egg is obtained from a human donor.
Stem cell research ethics
Stem cell therapies are far from affordable. So which side are you on? Basically, these are cells derived from blastocysts which are day old embryos. The debates over the ethics of stem cell research began almost immediately in , despite reports that stem cells cannot grow into complete organisms. The controversy stems from the consideration of ethics, revolving around the research process of embryonic stem cells that, simply put, involves creating and killing a human life. For those who believe that life begins at conception, the blastocyst is a human life, and to destroy it is unacceptable and immoral. Embryonic stem cells are important because they have several potential uses, from getting information about cell development to creating new drugs for medical disorders such as diabetes and cardiovascular disease. This stage of pregnancy is when many birth defects or other potential issues begin. They can be possibly used for organ transplantation. We can examine pluripotent cells, both induced and embryonic, to see what information is required for them to turn into a specific tissue cell.
The treatments developed from stem cells are experimental at the current phase of research. Basically, these are cells derived from blastocysts which are day old embryos. This means they cannot be changed into different cell tissues.
An example used is that of a patient who is comatose. As previously mentioned, embryonic stem cells are derived from human embryos.
